The Detroit-based automaker this week announced that Apple’s intelligent personal assistant’s “Eyes Free Integration” will expand to the 2014 Camaro, Cruze, Equinox, Malibu, SS and Volt. The system was previously available on Chevy Sonic, Spark and Spark EV models.

"The response to Siri Eyes Free integration in Chevy Sonic and Spark from our customers has been remarkable," said Chris Perry, Chevrolet vice president of U.S. marketing, in a statement. “Easy, reliable and portable connectivity is a top priority for our customers, and Siri complements MyLink's existing capabilities to help deliver an incredible driving experience, so we're excited to expand this to even more customers."

The system, which is compatible with iPhone users running iOS 6 or iOS 7 on iPhone 4S’ or newer, allows drivers to interact with their iPhones using nothing more than their voice. With a push of a button, drivers can talk to Siri and make voice-activated, hands-free calls to contacts on their iPhone; play songs in their iTunes libraries; listen to, and compose and send an iMessage or text message; and access their calendar and add appointments.

To use Siri, owners with the Chevrolet MyLink infotainment system connect their iPhone with the radio via Bluetooth, pair with the system, and use the steering wheel voice activation button to begin and end sessions with Siri in Eyes Free mode.

Most smartphone owners can also download the RemoteLink Mobile App, which allows current OnStar subscribers to control and manage certain vehicle functions from their phone.
